Memory leak with `rest/block` REST endpoint and `getblock` RPC when verbosity >=2 about bitcoin HOT 6 CLOSED

I could not reproduce an OOM, although I did observe resource usage increasing a little before eventually plateauing.

I see the same kind of behavior with Ubuntu with REST, the memory usage saturates after a few calls. So it looks like the same issue as in #25229 - at least for me.

Did the same check with

valgrind --tool=massif ./src/bitcoind &
while sleep 3; do ./src/bitcoin-cli getblock 00000000000000000002a7c4c1e48d76c5a37902165a270156b7a8d72728a054 2  ; done

...

massif-visualizer ./massif.out.1234

Is this a duplicate of #25229 (comment) ?

Related #24542 ?

I measured resident set size using python's psutil module, whilst making 2500 REST requests for random blocks in the blockchain between block 0 and 842460. The node was in blocksonly mode, and had no peer connections.

I haven't investigated any deeper than this yet.

Closing for now, as duplicate
